My sister in law ( visiting from Florida ) was checking out my tank today when she asked " what's this thing crawling around in that coral? " ,.... Huh ? Upon further investigation I discovered a small 1/2" + rusty colored heavily bodied crab with white tipped claws living amongst one of my acroporas !! Wow,... Never seen it before ,... I tried to get a picture but it's almost impossible to do at this point,... So weird to see something in your tank that you know you didn't put there,..I'm sure it must have been a hitchhiker on some coral or rock that I added along the way .
Kinda makes you wonder what the heck else is in there ? Pretty cool to see after having a crappy day up to that point.

I think I saw once that a reef has more life per square foot than anywhere else on earth. I found that doing macro photography on the reef was more fascinating than taking pictures of the big fish. Everything is alive. That's why I am a reefaholic, our tanks are doing the same thing.

I was really fascinated snorkeling last month looking at the same thing you're talking about ..., I came over the top of this large rock and was mesmerized by all the little tiny creatures that 99.99 % of everyone would have passed by ., the more you looked the more you saw ,.. But it's kind of hard to focus on something like that when a two foot long rainbow colored parrot fish swims by and gives you the stink eye

I was a dive master for a while and did a bit of underwater photography instruction. As they rest of the group paddled around chasing those parrot fish, we would settle to the bottom, pick a spot and wait. If you slowed down your breathing, stuff would magically appear. An amazing assortment of critters. What's even weirder is I have a pathological hatred of bugs. But I don't react that way to the sea life. My wife tells me I am complicated.

Some of those moray pictures I posted took up to an hour to get as I coaxed the eel out with a bit of fish. While patiently waiting you can't count the number of different tiny things you see.

As to the stink eye, he probably didn't approve of your color or body shape.
